1General
1.1 Safety information
ATTENTION
Installation should only be carried out by a qualified electrician!
1.2 Proper use
The DALI button interface TA 4 S DALI-2 is a compact DALI-2 controller with 4 inputs for
connecting potential-free buttons and 2 inputs for connecting variable resistors, e.g. sliders,
potentiometers or various Theben temperature sensors. It can be easily installed in flush-
mounted boxes and is intended for indoor installation.
TA 4 S DALI-2 is exclusively intended for use as contractually agreed between the manufacturer
and the user. Any other use is considered to be unacceptable. The manufacturer does not accept
liability for any resulting damages.
1.3 Explanation of terms
The TA 4 S DALI-2 DALI button interface is a push button processing unit of an input control
device according to standard IEC 62386 Part 301 as well as an absolute input device according
to standard IEC 62386 Part 302 and DiiA Guidelines "Clarifications & Recommendations for IEC
62386" Version 1.2, April 2020.
The term push button processing unit of an input control device is used in this document in the
English spelling "push button input device", absolute input device as "absolute input device"
and short address as "short address".

Manual DALI button interface TA 4 S DALI-2 4
2Function description
The TA 4 S DALI-2 button interfaces are integrated into a DALI system. Thanks to the DALI-2
standard, an application controller from any manufacturer may be used. This controller must
support standard IEC 62386 Parts 101/103/301 – and if variable resistors or temperature
sensors are used – also Part 302.
The TA 4 S DALI-2 button interfaces and other DALI components are connected to the DALI line.
The DALI supply is provided by the application controller or an external DALI supply. The
assignment of the short addresses (random addressing) for the button interfaces is carried out
via the application controller.
After start-up, the TA 4 S DALI-2 button interface captures the binary states of the connected
buttons and transmits this information to the higher-level controller (application controller) as a
DALI telegram. If variable resistors or temperature sensors are connected, the measured values
are transmitted to the higher-level controller as a DALI telegram (absolute input device).
2.1 Application examples
Application with a higher-level controller
Conventional buttons, sliders and Theben temperature sensors can be connected to the TA 4 S
DALI-2 button interface for the desired application, also for blinds, lighting control, heating
control, etc.

Manual DALI button interface TA 4 S DALI-2 5
Application with a DALI-2 presence detector
For switching or dimming lamps, conventional buttons are connected to the TA 4 S DALI-2
button interface.

Value range of offset
The offset can be used to correct the measurement value if, for example, the measurement
deviates from a reference device.
•The setting range is 0x01 to 0xFF; this corresponds to an offset range of
o{-12.7 °C to +12.7 °C} or
o{-12.7 kΩ to +12.7 kΩ}
•One unit corresponds to 0.1 °C or 100 Ω
Value range "Range":
The "Range" parameter can be used to select temperature sensors with a positive or negative
temperature range.
•0x00: Temperature sensors with a positive temperature range (factory setting)
•0x01: Temperature sensor with a negative temperature range
See also chapter 8.5 Measurement values T1/T2
Value range "Hysteresis":
The "Hysteresis" parameter can be used to reduce the DALI bus load. The event telegrams are
not sent until the measurement value has changed by the value of the set hysteresis.
•The setting range is 0x00 to 0xFF; this corresponds to a hysteresis range of
o{0.1 °C to 25.5 °C} or
o{100 Ω to +25.5 kΩ}
•One unit corresponds to 0.1 °C or 100 Ω

Value range "Filter":
For noise reduction, the filter level can be adjusted. The filter number determines from how
many measurement values the average value is calculated.
•The setting range is 0x00 to 0x0B
The filter delays the measurement. With a filter number of 0x02, the delay is about 0.2
seconds and with 0x0A about 51.2 seconds.
delay [ms] = 2filter number * 50 ms.
Value range "beta low/beta high":
If 0x02 has been selected at the sensor type parameter "NTC with known B or Beta", the
associated B or Beta [K] should be set here. B or Beta is a four digit number in [K], which can be
found in the NTC sensor data sheet. In order to be stored in the memory bank, the four-digit
number must first be converted to hex format and then stored in the beta low and beta high
bytes.
Example: B or Beta = 4580 which corresponds to Hex 11E4
•Beta low = 0xE4 factory setting
•Beta high = 0x11 factory setting
•The setting range for beta low is 0x00 to 0xFF and for beta high 0x00 to 0xFF.

8.3 Assignment of short addresses
The assignment of short addresses for the TA 4 S DALI-2 button interface is carried out
according to IEC 62386-103. The identification of the button interface is indicated by the LED
according to IEC 62386 Part 103.
LED
8.4 Button function C1-C4
The TA 4 S DALI-2 button interface has four instances to the button states:
- Instance 2 supplies the state of button C1
- Instance 3 supplies the state of button C2
- Instance 4 supplies the state of button C3
- Instance 5 supplies the state of button C4
on the DALI bus in accordance with IEC 62386 Part 301.
8.5 Determining measurement values T1/T2 via the DALI bus
The TA 4 S DALI-2 button interface has 2 instances to the measurement values of the connected
sensors:
- Instance 0 supplies the measurement value of sensor T1
- Instance 1 supplies the measurement value of sensor T2
on the DALI bus in accordance with IEC 62386 Part 302.
According to DALI standard IEC 62386-103/302, the value of an absolute input device instance
is obtained either by querying directly or by evaluating the events.
8.5.1 Direct queries
The following steps must be carried out in order to query the value directly:
1. Address the DALI telegram "QUERY INPUT VALUE" to the desired device and with the desired
instance number of an absolute input device.
2. Multiply the returned value by 4 and save it in a variable of at least 16 bits.
3. Address the DALI telegram "QUERY INPUT VALUE LATCH" to the previous device with the
previous instance number.
4. Divide the returned value by 64 and add it to the previous variable.

Manual DALI button interface TA 4 S DALI-2 17
Example as pseudo code:
Input value = QUERY_INPUT_VALUE ()
Variable = input value × 4
Input value = QUERY_INPUT_VALUE_LATCH ()
Variable = variable + input value ÷ 64
8.5.2 Evaluating events
An event of an absolute input device can be triggered cyclically or at a certain change of the
value. Depending on the type of sensor used, the following steps are necessary to display the
obtained value:
Temperature sensor with a positive temperature range:
Setting in memory bank 3: sensor type = [0x00], [0x01] or [0x02]
Setting in memory bank 3: range = [0x00]
Temperature measurement value [°C] = event info/10
Temperature sensor with a negative temperature range:
Setting in memory bank 3: sensor type = [0x00], [0x01] or [0x02]
Setting in memory bank 3: range = [0x01]
Temperature measurement value [°C] = (event info – 250) / 10
Variable resistor:
Setting in memory bank 3: sensor type = [0x03]
Measurement value [Ω] = event info x 100
